Overview
ETE DERBA is a secondary treatment plant in Salvador, Bahia, Brazil, serving a small population of 1,118. It discharges 120.82 cubic meters of treated wastewater and is located within 10 km of the coast.
ETE DERBA is a wastewater treatment plant located in Salvador, the capital of Bahia state in northeastern Brazil. Situated in the Região Metropolitana de Salvador, the plant serves a small population of approximately 1,118 residents, reflecting its role in local sanitation infrastructure. The plant provides secondary treatment, which is the standard biological treatment stage required under Brazilian regulations (CONAMA resolutions) for most municipal wastewater. Secondary treatment typically involves biological degradation of organic matter followed by sedimentation. The plant discharges a reported volume of 120.82 cubic meters of treated effluent. The treated effluent from ETE DERBA ultimately reaches the Atlantic Ocean, as the plant is located within 10 km of the coast. The receiving water bodies include local streams and the Baía de Todos os Santos, a large tropical bay known for its rich biodiversity and mangrove ecosystems. The plant's coastal location necessitates careful management to protect marine water quality and sensitive coastal habitats.
Environmental context
ETE DERBA discharges into the Baía de Todos os Santos watershed, a large tropical bay on the Atlantic coast of Brazil. The bay supports diverse marine life, including mangroves, coral reefs, and fish populations, and is an important area for local fisheries and tourism. The plant's coastal proximity means its effluent can directly influence nearshore water quality and ecosystem health.
